This verse represents the start of a major new section of the book of Genesis. The genealogy of Terah continues unto Genesis 25:11. It spans the entire story of Abraham’s life. One might wonder why Abraham’s story falls under the heading of Terah. The Lord thereby shows that the calling of Abraham is an act of his love and grace. When we pay attention to these people, it becomes evident what a miracle it is that Abraham produced God’s people and the Saviour. The name Terah points to the fact that Abraham came from a family in which idols were also served. We read about this in Joshua 24:2, “... and they served other gods.”
Abraham and Israel could not boast in their lineage.
Terah had three sons: Abram, Nahor and Haran. The text mentions that Haran was Lot’s father and we will encounter Lot a little later on in history.
Genesis 11:28 clearly shows that Haran had already died by the time Abram and Lot left Ur. This clarifies why Lot and his family went to Canaan with his uncle Abram. Lot was no longer bound to his father’s house.
Abram and Nahor both also marry. The names of their wives are Sarai and Milcah. The little bit of information briefly mentioned in Genesis 11:30 is of vital historical significance. We read there that Sarai was barren. It appears that it is impossible for Abram and Sarai to have children.
27 Now these are the generations of Terah. Terah fathered Abram, Nahor, and Haran; and Haran fathered Lot.
